Application filed May 28, 1919. Serial No. 300,358.

ToaZZ whom t may concern:

Be itpknown that l, DANIEL VANZILE, a citizen of the United States, residing at Vredenburgh, Alabama, have invented a certain new and useful lmprovement inl team-Feed Valves, of which the following is a full7 clear, and exact description, such as will enable others skilledy in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification. s

My invention relates to a steam feed or control. valve, and .while particularly designed for use in connection with the steam feed cylinders of saw mills, can be advantageously utilized wherever it is desired to positively control the feed of fluid pressure to ay cylinder or the like and to permit the exhaust of said fluid pressure from said cylinder.

rilhe valve herein illustrated and described is an improvement on the steam feedy valve disclosed in my copending patent application on steam feed valve control mechanism, filed March 24, 1919, Serial Number esame.

AIn my application aforesaid, they valve proper is secured to the valve stem by one 'or more nuts which are arrangedon threadbecome loose and in order to tighten them the upper part or head of the valve must be removed.

It is the principal object of my present invention to overcome the objectionable features just noted and provide a relatively simple construction which will be effective in retaining the valve in proper position upon the stem and said retaining means being locked to the valve stem by a 'nut or the like which is located on the exterior of the valve housino and in which position it is readily accessible.

With the foregoing and other objects in view, my invention consists in certain novel features of .construction and arrangement of parts,;hereinafter more fully described l' l and claimed, and illustrated in the accompanying drawings, in which-4 Figure l is avertical section taken through the center ef a .valve of myl improved conp struction.

Fig. 2 is a perspective view of the valve stem'. f x

Fig. Slis a perspective'view of the sleeve lwhich isapplied to the valve stem-for reproper operative positaining the valve in tion thereupon.

' Referring by numerals to the .accompanying drawings, 10 designates the body or housing of the valve inv which is formed a vertically disposedV cylindrical valve chamber 11, the upper end of which is yclosed by a removable head or plate 12 in the center 'of which latter is' arranged a gland nut`13.

.Secured to thellowerend of the valve.

'zek

housing 10 Vis a tubularelbow '14: whichy Y serves as'an outlet forthe exhaust steam or fluid pressure passing through thevalve` and located'in the lower portion of said elbow is a gland nut 15, the same being in direct verticalalinement with gland 13."

Formed through the wall of valve housing 10 isa steam or fluid pressure inlet port 16 and secured 'tof said housing and communicating with said port is a` steam or fluid pressure` supply pipe 17 Formed through the wall of housing 10 and oppositely disposed 'with respect to'inlet port 1G vis a port 18 andconnected to the Vvalve housing and communicating with this port is a tubular connection 19 which leads to the steam cylinder or other structure to which .steam or fluid pressure is to be intermittently supplied.

rfhe stem of ymy improved valve com prises an elongated rod 20,' ypreferably having the same diameter throughout its length,

tion of the valve stem with its lower end f bearing directly on top of the valve 22. This sleeve is arranged to slide freely through gland nut 13 and its -upper end terminates adjacent to the threaded uppei' end 25 of valve stem 20. Seated on this threaded upper end of the valve stem is a nut 26 which, when tightened, bears directly on top of the sleeve 24 and the downward pressure imparted to the latter by said nut is transmitted to valve body `.22 and the latter is firmly held in proper position upon the valve stem with its lower end against the flange or collar 21. y

Screw-seated on the upper end of threaded portion 25 and above nut 26 is a nut 2T with which is formed integral a loop or eye 2S and attached to the latter is one end of a cable 29 which is utilized in raising the valve stein and parts carried thereby. The lower end of the valve .stem is threaded as designated by 30 and seated upon said threaded end is a nut 31 provided with an integrally formed eye 32 and to which latter is secured one end of a cable 33 which isutilized for pulling the valve stem and parts carried thereby downwardly. The cables 29V and 88 are connected to suitable valve operating mechanism, preferably of the type disclosed in my hereinbefore mentioned copending patent application.

When valve 22 is inits lowermost position, as illustrated in Fig. 1, the annular groove or recess 23 establishes communication between ports 16 and 18 and thus steam passes from supply pipe .17 through the valve and thence through pipe 19 to the steam feed cylinder of a saw mill or the like and when the steam supplied by the valve has done its work, the operating mechanism to which cable 29 is connectedis actuated, thereby raising the valve stem and valve 22 is carried into the upper portion of chamber. 11, thereby cutting off communication between the ports 16 and 1S but opening the `latter to that portion of the chamber below the valve 22 and as a result steam or fluid pressure will exhaust through port 18 and after passing Vdownwardly through the chamber 11 will exhaust through outlet 111.

In Vthe event that valve 22 should become loose in service, nut 26 is tightened to force sleeve 211 downward7 thereby maintaining valve 22 in rigid position upon the valve stem, and as nut 26 is readily accessible such adjustment or take-up can be very easily and qiiiclrlyaccomplished.

A valve of my improved construction is comparatively simple, can be very readily adjusted to take up wear or lost motion, and can be very easily and cheaply manufactiired. y y,

lt will be readily understood that minor changes in the size, vform and construction el' the various parts of my improved valve can bey made and substituted for those herein shown and described, without departing troni the spirit of my invention, the scope of which is set forth in the appended claim.

That I claim is:

Y ln a valve ofthe class described, a hous.

ing provided with ports and a valve chamher, a valve arranged for operation within said valve chamber for communicating with said ports, a valve stem passing through V said valve and having bearings in the upper and lower portions of the housing, the ends of the stembeing screw-threaded, a shoulder on said valve stem against which the valve engages, a sleeve on the upper portion of the valve` stein` which sleeve bears against Y die valve and is arranged to slide through the bearing in the upper portion of the housing, a nut for locking said sleeve and valve unen the stem, and a iiutprovded with an eye or loop on each end of the stem to which may be secured operating cables.

In testimony whereof I hereunto affix my signature this 22nd day of May, 1919.
